Serena Williams Talks Grunts With David Letterman, Video. Coming off her recent Wimbledon win over her sister, Serena took some time to sit down with funny man David Letterman. Of course the topic moves to her and her sister’s grunts. The grunts have moved from just playing Tennis, to Soccer, to many things, but not breakfast.

To add to her point, I am 100% positive that proper European girls are most likely scared out of their wits when the Williams Sisters come to play. Serena is one of the most muscular women I have ever seen ( that does not body build and look grotesque ), and she is out there rushing the net and grunting whilst the dainty girl on the other side of the net most likely just got done with her tea and scones.
